Demonfall Codes (September 2026)

Demonfall puts you on either the demon slayer or demon side of a Demon Slayer-inspired world on Roblox, where you level up, fight through quests, and collect gear. Fireheart Studio occasionally hands out promo codes that unlock free cosmetics, giving your character a fresh look without extra grinding.

Working Demonfall codes

Two codes are currently redeemable, and both unlock the Sabito Haori cosmetic for your character.

How to redeem codes in Demonfall

Codes are entered through the settings menu rather than the chat box. Follow these steps inside the game.

Launch Demonfall in Roblox and load into a server.

Press the Tab key on your keyboard to bring up the menu overlay.

Click the gear-shaped Settings icon that appears.

Scroll to the bottom of the settings panel until you see the Promo Code field.

Type or paste the code exactly as shown, since codes are case-sensitive.

Press Enter to claim the reward. A successful redemption adds the Sabito Haori to your inventory right away, and you can equip it from your customization menu.

Expired Demonfall codes

These codes used the older chat-command format and no longer work in the current redemption system.

Where new Demonfall codes get announced

Fireheart Studio typically shares new codes around updates and bug fixes rather than on a fixed schedule. The official Demonfall Discord server and the Fireheart Studio Roblox group are the two channels where these announcements appear first.

Note: if a code shows an error message right after a game update, wait for the servers to fully refresh before trying again, since new codes sometimes take a few minutes to activate account-wide.
